Support connector lock

ABSTRACT

An improved roller shade system provides increased support, additional adjustments and/or increased safety. The slip plate allows the brake to slip forward and minimize damage to the clutch spring when a user pulls too hard on the hembar. The center drive mechanism extends through a bracket to allow the drive shaft to distribute power in both directions and drive two shade tube simultaneously. The tube adapter absorbs force from the spinning shade tube to minimize damage to the other components and the bead chain. The sprocket has a back wall supporting the sprocket, allowing the sprocket  130  to rest on the back flange of the sun gear to minimize pressure on the gears. An adjustment arm is adjusted to help level the shade band. The shade bands may be removed without disturbing the other shade bands in the system. A height of a hembar may be adjusted by rotating a rod within the hembar.

TECHNICAL FIELD

This disclosure generally relates to improvements to various functions and features of roller shade systems.

BACKGROUND

With reference to FIG. 1 , roller shade systems 100 typically include a window covering attached to a shade tube 105, wherein the window covering rolls up onto a shade tube 105. The shade tube 105 is mounted between brackets 125 and at least one of the brackets 125 is connected to a series of mechanical components such as gears, bearings, clutches, shafts, sprockets 130 and hubs. A bead chain is mounted onto the sprocket 130. Pulling on the bead chain rotates the sprocket 130, which opens up the clutch (e.g., spring). Opening the clutch allows rotation of a driving hub attached to the tube. The driving hub rotation rotates the tube which lowers (or raises) the shade. The clutch may include a wrap spring such as the wrap spring disclosed in U.S. Pat. No. 6,164,428 for “Wrap Spring Shade Operator”, which is hereby incorporated by reference in its entirety for all purposes.

SUMMARY

DETAILED DESCRIPTION

In various embodiments, and as set forth in FIG. 1 , a shade system 100 may include a first shade tube 105, a drive hub 110, a drive shaft 115, support bearing 120, shade bracket 125, sprocket 130, a bead chain (not shown) that rotates around the sprocket 130, a brake hub 135 (that includes a sun gear 140), planetary gears 145 surrounding the sun gear 140, a planetary carrier 150 for the planetary gears 145, a wrap spring 165 in the brake hub 135 (shown in FIG. 2B), a bearing shaft 155, a drive hub 110 and a second shade tube 105. In various embodiments, the system may include one or more improvements such as a slip plate 170, center drive mechanism, tube adapter 160, back wall 200 on the sprocket 130, adjustment arm 215, shade band removal system and/or hembar 245 adjustment device, all of which are further described in detail below.

In proper operation, as initially set forth in FIG. 1 , and in response to pulling the chain, the clutch (e.g., wrap spring) retracts away from the inside of the brake hub 135 to allow the brake hub 135 to rotate (and thus sprocket 130 to rotate) such that the chain around the sprocket 130 can be pulled down. Conversely, in response to the pulling force being released, the spring re-engages with the inside of the brake hub 135 and the wrap spring stops the rotation of the shade. In prior systems, the brake hub 135/sun gear 140 is permanently affixed to the bracket 125 and the planets rotate around the sun gear 140. Therefore, when users pull on the shade or hembar 245 (FIG. 9A) of the shade (i.e., back-driving the clutch) with too much force, the clutch components (e.g., wrap spring 165 (FIG. 6 ), brake hub 135, gears, etc.) may be damaged or break.

To help solve this problem, the system may include a slip plate 170 to avoid or minimize damage. In particular, with respect to FIGS. 3A and 3B, in various embodiments, the system may include a slip plate 170 (also known as a detent clutch or slipper clutch) engaged with the brake hub 135 (e.g., but not permanently affixed to the brake hub 135). In particular, the slip plate 170 includes any number or size of tangs 175 that engage with the brake hub 135, wherein the tangs 175 are received within any number of slots in the brake hub 135. The slip plate 170 allows the brake hub 135 to ratchet or slip forward any number of degrees (e.g., 90 degrees to the next slot, as shown in FIG. 3B) to reduce or avoid breaking the clutch components. The tangs 175 of the slip plate 170 may include any number of “protrusions” 180 and “fingers” 185. For example, the slip plate 170 may include four “protrusions” 180 that extend outward from the shade bracket 125 and into four “pockets” (or slots 190) in the brake hub 135. The 4 respective “fingers” 185 are received into the shade bracket 125 to hold the slip plate 170 against the shade bracket 125. When the user pulls the shade or hembar 245 with excessive force, the protrusions 180 pop out (or flex out) of their pockets 190 in the brake hub 135, thus allowing the brake hub 135 to “slip” forward and rotate (e.g., 90 degrees), until the knuckle 180 is caught again in the next pocket 190. The user may feel a ratcheting action as the protrusions 180 rotate through the “pockets” 190 while the force is applied. When the brake hub 135 slips forward, any portion or all of the drive mechanism (e.g., the sun gear 140 (that is part of the brake hub 135), planetary carrier 150, the bearing shaft 155, the drive hub 110, the tube adapter 160 and the shade tube 105) also slip forward to minimize or avoid breakage. However, the ratcheting action may not affect the relationship between the bead stop locations and the resulting hembar 245 position.

When a user pulls a shade too quickly and it reaches an end limit, a bead stop on the chain hits the bracket 125 housing and stops suddenly, which occasionally leads to the chain snapping. In particular, the chain sometimes breaks because the clutch does not close immediately, so the momentum of the shade tube 105 and fabric back-drives from the shade tube 105 through the tube adapter 160, through the drive hub 110, through the brake (which has not closed yet), into the sprocket 130, and causes excessive forces on the chain. Such back-drive may occur in the milliseconds before the clutch can close the brake and stop the system. The back-drive is what causes the sprocket 130 to continue pulling on the chain after the chain stops on the bead stop, thereby breaking the chain. In other words, the shade tube 105 may still spin due to momentum and because the clutch may stay open for a fraction of a second, even after the bead on the chain hits the stop point. The spinning of the shade tube 105 may exert torque on various components of the system and the chain may break. Other systems may include a bumper on the bead stop to act as a shock absorber, but such a bumper placement is often insufficient to prevent damage, the bumper placement is unsightly and/or the bumper placement gets in the way of various forms of chain guides.

As such, with respect to FIGS. 5A and 5B, in various embodiments, tube adapters 160 dampen the torque and absorb some of the force from the spinning tube. In particular, the flexible and soft tube adapter 160 dampens some of the force back-driving from the shade tube to the drive hub 110 and subsequently through the rest of the drive train. The tube adapters 160 help to protect the components and mitigate chain breakage. The tube adapters 160 minimize or prevent damage to the clutch, sprocket 130, chain, bead-stop, and/or housing of a drive bracket 125 due to excessive rotational speed of a shade being raised or lowered. The tube adapters 160 may be any dampening material such as, for example, urethane. The tube adapter 160 may be any shape or size. In various embodiments, the tube adapter 160 is sized and shaped to engage with different tube sizes and shapes. In various embodiments, the tube adapter 160 may be incorporated inside the clutch mechanism to further dampen and prevent chain breakage. For example, the drive hub 110 on the tube adapter 160 is typically rigid. However, the tube adapter 160 may include a semi-rigid element that has a limited amount of flexibility in the one or more tabs (on the drive hub 110) that drive the hub. This semi-rigid element of the drive hub 110 may have a certain amount of shock absorption built into the element. This semi-rigid element resides inside the brake hub 135, which may not be in the tube.

As shown in FIG. 1 , in various embodiments, the sun gear 140 is a stationary component that allows the planetary gears 145 (that are held by the planetary carrier 150) to rotate around the sun gear 140 clutch. The planetary gears 145 rotate within the sprocket 130 (ring gear), so the load on the chain pulling on the sprocket 130 is typically pushing down on and putting weight on the planetary gears 145. This arrangement causes the sprocket 130 and planetary gears 145 to be off-center and wobble. As such, with respect to FIG. 6 , in various embodiments, the system includes a “back wall 200” support on the sprocket 130 that provides support for the sprocket 130. In various embodiments, the back wall 200 may engage any element that is concentric to the sun gear 140, thereby supporting the load from pulling the chain. For example, the back wall 200 includes an opening of a smaller radius, so the back wall 200 sits on a flange (e.g., non-toothed portion) on the backside of the sun gear 140. As such, when the chain pulls down on the sprocket 130, at least a portion of the inner circumference of the opening in the back wall 200 of the sprocket 130 pushes against the flange 205 on the backside of the sun gear 140, and does not put pressure on the planetary gears 145. This arrangement keeps the brake hub 135/sun gear 140 centered and prevents wobble that leads to smoother operation. Having the brake hub 135 integrated with the sun gear 140 also makes for a smaller package and reduced quantities of system components.

When multiple shades (e.g., 2-6 shade bands) are installed next to each other across a large window, each shade would typically need its own drive bracket 125 (with its own sprocket 130, chain, etc.) that controls the movement of the single shade. A shading system may also include a multi-banded system in which a multitude of individual shadebands are driven by a single manual drive chain or motor that interfaces with a first shade. A shade band may consist of a shade tube 105, tube adapters 160, and a fabric band. The fabric band may comprise a spline (which may be welded to the top of the fabric) and the hembar 245 (which may be attached to the bottom of the fabric). In various embodiments, the system drives multiple shade bands through a single chain by using a support connector 210 (e.g., multi-band coupler between two shade bands). The support connector 210 fits within an accompanying bracket 125 between each shadeband. A single drive bracket 125 may be configured at one end of the group of shadebands being controlled. Pulling on the chain drives a first shadeband attached to the drive bracket 125, which is coupled to two or more shadebands, wherein each band is driven via a support connector 210 in a serial fashion from the first shadeband.

At times, one shade in the multi-banded system may need to be removed due to service or maintenance. However, if the shade band attached to the drive bracket (the bracket with the sprocket and clutch/brake mechanism) is removed, then all the shades may unroll because the clutch system at the drive bracket 125 is no longer restricting the shade tube 105 rotation. Moreover, if a second shade in a multi-banded system is removed, then the third shade, fourth shade, etc. may also unroll because, while the clutch system may still restrict the first shade, the clutch system is no longer restricting the shade tube 105 rotation in the subsequent shades. To prevent the shades from unrolling, some service people would tape the hembar 245 onto the rest of the window shade roll. However, the use of tape is often unreliable and requires additional time and effort to tape each individual shade. In various embodiments, the present system may allow an individual shade band in a multi-banded system to be removed without disturbing the rest of the bands in the system. Prior to a shade band being removed, any subsequent bands would be locked into place. The system may include a lock to prevent the shade tube 105 from unrolling when other shades in a multi-banded system are removed. The lock may be any device that restricts the rotation of the shade band and/or support connector 210. For example, a slide lock 240, a fork, pin or pawl that interfaces with the shade tube 105 and/or support connector 210. A slide lock 240 is shown in FIGS. 8A and 8B, wherein the support connector 210 extends through the slide lock 240 that includes a larger opening (that allows rotation in FIG. 8A) and a restricted opening (that restricts rotation in FIG. 8B). When the slide lock 240 is in the down position, the support connector 210 extends through the larger opening such that the support connector 210 is able to rotate. When the slide lock 240 is in the up position, the support connector 210 extends through the restricted opening such that the support connector 210 is restricted from rotation.

Moreover, the center-support brackets 125 in a multi-banded system typically include a support connector 210 that goes through the center-support bracket 125, such that a first shade tube 105 interfaces with the support connector 210 on the first side of the bracket 125 and a second shade tube 105 interfaces with the same support connector 210 on the second side of the bracket 125. This arrangement may repeat for subsequent shades in a multi-banded system. Because of this arrangement, when service personnel needs to remove, for example, a third shade band, they first need to remove the first shade band and the second shade band in order to be able to remove the third. In various embodiments, the present system provides a support connector 210 configured to be removed or moved out of the way, such that any shade band can be removed, without needing to remove the other shade bands. For example, the center-support connector 210 may be comprised of two shafts that interface with each other at the middle of the center-support bracket 125. These halves can individually be retracted into its respective shade tube 105, thereby allowing the shade band to be removed independently. In another example, the system may have the support connector 210 be a single shaft that can slide into either the first shade tube 105 or the second shade tube 105 in their respective shade bands on either side of the center-support bracket 125.

There are times when obstacles in the room (e.g., couches, tables, desks, etc.) could be obstructing access to the chain used to operate the group of shades in a multi-band arrangement. The chain may be hidden behind a column or recess preventing easy access to the chain in order to operate the shade. As such, with respect to FIG. 4 , in various embodiments, the system may employ a center-drive mechanism such that the chain now is positioned at a location within the shade group where there is no obstacle obstructing access to it. The center drive mechanism may comprise a hole in the bracket 125 and the drive shaft 115 that goes through the bracket 125 (the drive shaft 115 can be any shape capable of transferring torque (e.g., hexagonal)). The drive shaft 115 controls the first drive hub 110 (on the left) that rotates the first shade and also controls the second drive hub 110 (on the right) that rotates the second shade. As such, when the one chain is pulled to rotate the sprocket 130/ring gear, the single drive transfers the rotational force to two shades on either side of the drive bracket 125. In other words, the center drive mechanism drives two bands of a shade in multi-band system via one central sprocket 130 where the two bands, on either side of the drive bracket 125, are driven in a parallel manner (as opposed to a serial manner). Either or both of the shade bands (on either side of the bracket 125) may themselves include a support connector 210 (as described above) on the end opposite of the drive bracket 125, so the center-drive mechanism may drive more than one shade on either or both sides of the bracket 125. In that regard, the center-drive mechanism may not necessarily be in the center of the various shade bands (e.g., may have 1 shade band on the left, and 2 coupled shade bands on the right).

In the past, installers would use a shim with the bracket 125 to try to align the brackets 125 when mounting the brackets 125, for example, on an uneven ceiling. The installers would place one or more shims of various thicknesses between the ceiling and the top mounting flange of the bracket to lower all brackets to the same level as the lowest bracket in a group. However, the installers would need to create and/or carry different shims. To try to minimize or avoid the use of shims, the installers may adjust a set screw that engages with a support connector 210 (e.g., at a center support in a multi-banded arrangement, as shown in FIGS. 7A-7D) and/or a set screw that engages with a shade band at an idle end (as shown in FIGS. 7E-7H). For example, a support connector 210 typically rests within a support connector 210 holder on the bracket 125. The support connector 210 holder is mounted with a fastener within a channel such that the support connector 210 holder may be configured to move up or down. A shade bracket 125 would include a screw below the support connector 210 holder and pushing against the support connector 210 holder, wherein turning the screw would raise or lower the support connector 210 holder. A similar set screw arrangement existed for a shade band at an idle end. In particular, shade systems would use a moveable element that supports the center-line of a shade. This moveable element rests on a screw via gravity alone. Adjusting this screw adjusts the centerline up and down. Such adjustments were used to even out the shade band to make the shade parallel to the window sill or to compensate for an uneven ceiling. However, such a screw assembly has disadvantages including that the assembly is underneath the unit, so the assembly increases the overall height of the bracket and takes up more space, especially inside a pocket.

As such, with respect to FIG. 7A-7I, in various embodiments, the system includes a cam type pivot system (e.g., adjustment arm 215) to even out the shade band and adjust the centerline of a shade system. The adjustment arm 215 may include a first portion, a middle portion and a second portion. The middle portion of the adjustment arm engages the shaft, an adjustment screw engages a first portion of the adjustment arm and the second portion of the adjustment arm comprises the pivot point. As shown in FIGS. 7A-7D, center support bearing 225 is located around at least a portion of the support connector 210. When the center support bearing 225 is moved up or down, the shade band on each side of the bracket 125 also moves up or down. Similarly, as shown in FIGS. 7E-7H, when the shaft on the idle end band is moved up or down, the shade band including the lam spring 235 also moves up or down. The adjustment arm 215 allows for height adjustment by a swinging arc that may be self-locking and indexing. The system employs a centerline adjustment arm 215 that is used on the idle end to avoid the gears, and in order to ensure the centerline can be leveled for each band independently. The adjustment arm 215 allows for a curved path of travel for the center-line. The centerline translates horizontally as well as vertically. By having a cam like device, the pathway can be straight, vertically up and vertically down (without curving too much horizontally). Also, most screws (described above) have the adjustment mechanism resting below the support connector 210 or the idle end shaft. In the present device, as shown in FIG. 7I, the adjustment screw 220 is resting on the side (e.g., head) of the adjustment device. As shown in FIG. 7G, a spring-loaded locking pawl 230 retains the support connector 210 or lam spring 235 at a certain level. In response to turning the adjustment screw, the support connector 210 or idle end band is adjusted, while the spring-loaded locking pawl 230 continues to retain the support connector 210 or idle end band in the newly adjusted location.

In various embodiments, and as shown in FIG. 7I, the head of the adjustment screw 220 has one or more flat cuts 222 into at least a portion of the head. The housing of the adjustment device is resting on the head, as shown in FIG. 7I. The flat cut 222 allows the rotation of the adjustment screw 220 to provide feedback in the form of a tactile and/or audible click. The feedback allows the rotation of the adjustment screw 220 to be indexed (e.g., every 180 degrees). The indexing gives the user a reference point for how many turns they have made. The flat cut 222 also prevents the adjustment screw 220 from back-driving or loosening (e.g., helps lock the adjustment screw 220 so that it does not turn on its own). In various embodiments, the system may also employ an adjustable dogbone-type coupling device allowing the system to level each shade band independently, as set forth in U.S. Pat. No. 7,625,151, which is hereby incorporated by reference in its entirety for all purposes.

Adjacent shade bands may not always be aligned vertically with each other, so the present system allows for adjustment of one or more hembars 245 to maintain visual consistency. In various embodiments, the system may also include mechanisms that allow the hembar 245 to be variably attached to the fabric. In various embodiments, as shown in FIGS. 9A and 9B, the bottom position of the hembar 245 is not fixed and can be shifted up (as in FIG. 9A) or down (as in FIG. 9B) to allow for adjustment of the hembar 245 vertically on the fabric 250. The fabric 250 at the bottom of the window shade may be rolled around a small tube 255 that can be rigidly fixed inside the hembar 245. Tube 255 may include a rod with a head that can be turned. For example, the head of the rod may include a hex head that can be turned with a hex key, a channel that can be turned with a flat head screw driver, or a cross-hair that can be turned with a screw driver having a head that is shaped like a fared cross with a rounded point. By rolling up a small amount of fabric 250, the position of the hembar 245 can be adjusted up or down vertically as it hangs from the bottom of the fabric 250.

The roller shade system may be controlled by a shade control system. As such, this application incorporates by reference for all purposes and in their entirety: U.S. Ser.
